[oXygen-user] mysterious new validation error in ODD-generated Relax NG XML schema

[Elisa Beshero-Bondar]

Many thanks to Jirka and Peter for their replies, which precisely
identified the problem with my ODD's Schematron rules testing sequences of
values. Jirka, thanks also for explaining why the error messages seemed so
random! I've implemented the changes each of you suggested and the schema
is validating properly now.

Cheers,
Elisa
